有机化合物的催速氢化,是在化学工业的各部门中被广泛采用的最重要方法之一。合成燃料的制造,树脂、芬香化合物的氢化,及为使液体脂肪硬化的油脂氢化等,在工业上都是很被重视的。催速氢化的理论当有催化剂存在时,氢气加合于不饱和化合物的作用显著加速。因此,可以设想触媒促进了氢分子及被氢化的物质的活化。有数种理论企图解释氢化过程中催化剂的作用,如某些科学家(法金Фокин,隆巴齐Сабатъе)设想氢化过程中形成了不安定的氢化物或是组成不定的吸附复合物。用镍作催化剂时,使不饱和化合物进行氢化的最简单的机构可表示为:
The rapid hydrogenation of organic compounds is one of the most important methods widely used in various sectors of the chemical industry. The manufacture of synthetic fuels, the hydrogenation of resins, fragrant compounds, and the hydrogenation of fats and oils to make the liquid fat harden, are of great importance in the industry. Theory of Hydrogen Pressurization Hydrogenation accelerates significantly when hydrogen is added to an unsaturated compound in the presence of a catalyst. Therefore, it is conceivable that the catalyst promotes the activation of hydrogen molecules and hydrogenated species. There are several theories that attempt to explain the role of catalysts in the hydrogenation process, as some scientists (Faktor Фокин, Lombok Сабатъе) envisage the formation of unstable hydrides or indefinite adsorption complexes in the hydrogenation process. When nickel is used as a catalyst, the simplest mechanism for hydrogenating the unsaturated compounds can be expressed as:
